Diagnosing client data (vmstat)

Two questions:

1. what's the format of [vmstat] ouput that the Hobbit server is expecting? The sar command is not available, so I'm substituting with iostat output that looks like:

[vmstat] cpu utilizaton stat using iostat:

0 0 0 0 0 0 0 0 0 0 16 1 0 13 0 0 0 100 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 100 0

where the 2nd last tine is the actual iostat output (iostat 300 2) and last line is what I think Hobbit is expecting. Tthe last 4 numbers, 0 0 100 0 are usr, sys, idle and iowait, that I parsed from iostat output.

2. on server side, how do we debug/trace when client data have arrived? There's hist, histlogs, hostdata, logs. I would like to see some reponse to events like: data arriving, data interpreted/extracted, etc.

Thank you,
